I just had a Bridgestone 709 with Dyna- Beads front tire put on my bike today. It was a premature tire replacement as I had a screw puncture on my 7,000 mile front Metzeler. I did the " hands off the bar " at 40 +/- mph on the way home and had no wobble, nada, zilch. I just recently put a car tire on the rear but the wobble was still there before I replaced the front tire.. This may be interesting to note : I asked the mechanic to install the Dyna-Beads and then put the tire on their wheel balance machine and see how it would do. Chris told me that the balance speed would probably not register any Dyna -Bead effect as they only " HAND SPIN " the tires. At what RPM they spin the tire to balance them is a matter of guess because I don't think they know either. How fast can you spin a tire on a balancing machine by hand ? I suppose it depends on how strong your shoulder and triceps muscles are. Food for thought.
